Thanks for the links Brian, it inspires my interest in math. This is not
IMHO not nearly off topic. I just did a upper rebuilt to my Vanagon and I
know it is not for the next 30 years but I am thinking, I did all that work
and now gas is so exspensive I can't aford to take the road trips in it that
I want. I am not proud of the gas miliage of the vanagon. Most of us seem to
be doing all this work ourselves maybe we ned to figure out a decent
afordable deisel convertion. so we are ready for the next wave of fuel if
bio fuel is the answer. I love the van but somtimes I think my energy should
be going into the next whatever....

  I am just frustrated at this situation I think I need to go ride my bike.
